STUDY ON THE MIXING PROPORTIONS OF HIGH BENDING STRENGTH MORTARS AND THEIR CHARACTERISTICS

Abstract

This paper is intended to study the mixing proportions of high bending strength mortars which have been developed recently and have been reported on this Transaction of AIJ No.492, 1997. 2. On this paper, the effects of the percentage of silica-fume, water binder ratio, sand binder ratio and the gain size of the sand were studied in order to grow up the bending strength of mortar. And the characteristics of these mortars were clarified, such as young's modulus, shrinkage, absorption, shockproof and fireproof properties.
